so fold KQ utg?

I have been consciencly (sp?) working on getting my vpip down and my pfr up but i find it really hard to play less hands.

I've also been actively trying to be more positionally aware and steal more. Over the last 10K hands or so my ats is 38%

I think lately I've been calling too many raises with suited connectors and weak broadway hands trying to out flop the guy. I should prob just fold these hands and tighten the fck up o_0

I really don't want to be a 10-8 nit playing 15 tables, is that the only way to win here?
